Non-surgical profi le correction in a class II malocclusion

Resumen

Case report of a 17-year-old male patient, skeletal class II, convex profile, not pleased with his facial appearance and without any intention to undergo surgical treatment. He presents severe protrusion and crowding, lip incompetence and protrusion, 7mm overjet and -3 mm overbite. The treatment goals were to improve lip relation and esthetics, establish a functional occlusion, to improve the profi le and muscular balance. Four fi rst premolar extractions were performed and anchorage control was accomplished with a transpalatal and lingual arch. Treatment results were very successful achieving functional occlusion, lip competence, mandibular rotation and a decrease in profi le convexity without surgical treatment. It is important to know the scopes and limits of orthodontic treatment regarding soft tissues, as well as maintaining anchorage to achieve profi le changes with maxillary incisor retraction.

Key words: Class II malocclusion, lip incompetence, mandibular rotation.
